MACHINE FOR MOLDIN'G- BUILDING-BLOCKS.

To alt' whom it may concern:

Be it known that I, JOHN R. VINSANT, a citizen of the United States of America, residing at Raydon, in the county of Hughes and State of Qklahoina, have invented new and useful Improvements in Machines for Moiding Building-Blocks, of which the following is a specification.

This invention relates to machines for molding building blocks, and one of the principal objects of the same is to provide a machine for the purpose referred to which will be quick in operation and which will form a compact building` block.

Another object of thc invention is to provide a machine for continuously forming building blocks of a moldable material, means being provided for pressing the blocks in the .mold blocks and for discharging the same quickly therefrom.

These and other objects may be attained by means of the construction illustrated in the accompanying drawing, in which,-

Figure lis a side elevation of a machine made in accordance with my invention. Fig. 2 is a plan view of thesame. Fig. 3 is a perspective view of one of the blocks formed in the machine, showing a mating block in dotted lines, said two blocks being disposed in position to form a wall having ventilatingl openings extending vertically therethrough. Fig. 4L is a vertical sectional view of one of the mold boxes in position at the right hand side of the wheel, the core being omitted.

Corresponding parts in the several figures are denoted by like characters of Ireference.

Referring to the draw-ing, the numeral. 1 designates the legs of a suitalole frame provided with a horizontal bar 2 upon which is journaled a shaft 3, said shaft extending through a skeleton wheel comprising radial arms 4 and supporting tables The shaft 3 is held in position by means of suitable keepers t5 bolted to the bars 2. Secured to each of the tables is a mold box 7, said inold box comprising a bottom 8,' a rear side wall 9, sides and front, all formed integral. Inside the box the cores 12 extend from the bottom to near the top of the box, and the space 13 forming the building block lfi receives the concrete or plastic material for forming said block at. theleft hand side of the wheel. as shown in llig. 1. A pallet is placed Within the box upon the top of the block.

Specification of Letters Patent. Application filed September 19, 1908.

Patented Aug. 2, 1910. serial No. 453,743,

At the right hand side, as shown in Fig. 1, springs 15 are secured to extensions of the bar 2, said springs having downwardly extending terminal hooks 15a forV holding the box -down againstI the upward movement of the follower 1G. Said follower, is mounted upon a vertical standard 17, the lower end of which is provided with a base 18 mounted on rollers 19. A spiral spring 20 surrounds the standard 17 and normally raises the follower 16. A tooth'ed rack 21 is formed in the follower, and at the upper end of said follower a presser head 22 is provided, said presser head being of substantially the same size as the mold box and designed for movement within the same. To raise the follower 1G in order to subject the block in the mold box to pressure, a lever 23 is provided, said lever being pivoted at 24C to a standard 35, said lever having a sector 26 formed thereon to engage the teeth of the rack 21. The standard is pivoted to a block 27 which is anchored in the ground or secured to the ioor of the building or structure where the device is installed. A curved groove or runway 28 is formed in the ground or in the tloor of the building in which groove the base or truck 18 of the follower 1(5.is mounted. A lever 29, pivoted at 30, to the standard is pro vided for moving the follower from under the mold box, said lever being conneeted'at' 31 to the follower and provided with a slot 32 through which the pivot 30 passes.

The operation of niy invention may be briefly described as follows: The boxes at the left hand side of Fig. 1 are filled with material for forming the building blocks 14, and when they are moved by rotating the arms t tothe right hand side of the machine.l the box is engaged by the springs or resilient members 15, whereby it may be held againstreverse movement, while the contents of the box is being subjected to pressure. lVhile the wheel is being turned, the pallet to which reference has hereinbefore been made, and which is indicated at 8'l in liig. It of the drawing, may be retained in posi ion by the hand of the operator or by retaining means of anysuitable and well known character. By actuating the lever 23, the follower '1 (3 is moved upward to press the contents of the box, and after the follower has been withdrawn the pressed block may be removed,

and the wheel may be further rotated, the follower' being meanwhile swung out of the way by means of the lever 29, whereby the V truck supporting said follower is moved in .the groove or runway provided for the purpose.

From the foregoing description it will. be seen that a machine made in accordance :with this invention can be operated quickly and efficiently to form building blocks ofthe characterv indicated.

said follower, a sector lever for engaging the rack a curved truck. and n lever for movimr 7 h the 1follower and the standard in said curved trac 2.'In a machine for formin building blocks, a wheel, a series of mol boxes-secured to the wheel, a follower mounted upon a standard, a curved track in which said standard is mounted, rack teeth formed on said follower, a sector lever engaued with said teeth, a pivoted standard, an a lever connected to said pivoted standard and to said follower for moving the follower `and standard in said curved track.

In testimony whereof I affix my signature in presence of two witnesses.
